Chess pieces for analysis board with 35 mm squares
The smaller size Chavets show up on eBay fairly regularly - I picked up a 0 and a 2 over the last year or so, with the idea that maybe I could adapt them to an e-board, or add magnets for travel use.

I'm going to buy this 8" Small Best Magnetic Chess Set from ChessUSA, as soon as they're back in stock. Seems like a perfect mobile analysis size board for cramped cafe tables.
Note: this set is available in several sizes, video review with size comparisons on ChessUSA is HERE
@RussBell Good to know WE Games chess equipment is available on eBay. I had seen WoodExpressions stuff online, but didnt find a retail vendor anywhere.
